APPARATUS FOR MANUFACTURING SOAP.

SPECIFICATION forming part of Letters. Patent ltToQ 224,514, dated February 17, 1880.

Application filedApril 29, I879,

To all whom it may concern:

Be it known that I, BENJAMIN H. C AD- BOURN, of the city, county, and State of New York, have invented a newand useful Improvement in Apparatus for Manufacturing Soap, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to that class of soapmaking apparatus in which the greaseor oil and alkaline matter are placed in a'digester or close vessel and formed into I soap by the verse section of the upper portion thereof,

showingthe mixing-chamber and agitator.-

A represents the base of the apparatus; 13, the furnace, and O a cylindrical mixing-chamber, through the center of which passes a shaft, D, carrying any desired number of radial arms E E E E. ing-bladesF F F F, whichare formed of iron bars or rods securely fastened to the arms E E E Eat their outer extremes, so that when the agitator revolves the outer edgesof said blades F F F F shall come within about onehalf inch of the inside of the cylinder or mixing-chamber. The ends of said blades should also extend equallynearto the inside ends of the mixing-chamber. V

The blades G G G G are made of angle-iron, and attached to the arms E E E E about midway between the shaft and the outer blades,

F FF F, the convergence-of the angle of each H H H H are propelling-blades of quadrant shape, their outer edges being arcs of ninety degrees, each made of light boiler-iron, and

To these arms are attached agitatsecurely attached to the arms E E E E as follows, viz: one set of two blades near the rearv end of the shaft and another set near the middle, and at such an angle, as to give a gentle motion to the contents of the cylinder toward the front end. t a

It has been the fault of all rapid agitation in soap-making to make the fatty and alkaline matters in the process-of saponification froth and foam, which must result in the production of a spongy imperfect soap." All danger of such a'result is obviated by the use of my improved agitator.

The number and size of the blades 13, G, and H will depend upon the size of the cylinder or mixing-chamber used and the quantity-0f soap to be made at a run.

For a cylinder of one ton capacity, being eleven feet long and thirty inches in diameter, the blades F F F F should be about three inches wide, and the blades G G G G should be made of about four-inch an gle-iron.

The periphery of the propelling-blades H H 'H H should run within about one inch of the Four of these blades,

This apparatus is capable of making a ton of superior quality of soap in ninety minutes, to produce which the agitators should be made torevolve from fifteen to eighteen times a minute. i

The process of making by means of the foregoing-described apparatus is as follows: The 7 materials out of which the soap is to be made The cylinder formed, which can be ascertained by'means of a try-cock. The soapis then blown out of the cylinder by the steam-pressure, and conveyed through conducting-pipes to the crutching machines or other receiving-vessels.
